🔍 Key Concepts

• Relationship between speed, frequency, and wavelength in electromagnetic waves (c = fλ) • Standard approximate value of the speed of light in a vacuum in meters per second • How metric prefixes (kHz, MHz, Hz) change the numerical value of frequency and therefore the constant used

💭 Think About

• Start from the basic wave formula and solve it for wavelength in terms of frequency. • Think about what happens to the numerical constant when you express frequency in kHz vs MHz vs Hz but still want wavelength in meters. • Ask yourself whether each option is just a different way of writing the same physical relationship using different units, or if any of them would give a different wavelength for the same real-world signal.

✅ Before You Answer

• Convert kHz, MHz, and Hz into plain Hz and see what factor of 10^3 or 10^6 you introduce. • Check that in each choice, using a realistic radio frequency (e.g., 3 MHz or 3000 kHz) gives you a wavelength close to what you expect (in meters). • Verify that the speed of light value implied by each formula is approximately 300,000,000 m/s.

Question 1 of 20

The formula for determining the wavelength when the frequency is known is:

Wavelength = 300,000/ f kHz

Wavelength = 300,000,000/ f Hz

Wavelength = 300/ f MHz
